RecyclerView IndexOutOfBoundsException 问题

在项目中遇到一个RecyclerView 偶现的奔溃，查看日志，发现是：

猜测原因是，RecyclerView的对于的数据被更改，比如，RecyclerView 当前的List 的size是39，然后，把这个List 删除了一部分，这个操作没有及时调用RecyclerView的notify造成了。

由于项目这个List修改的地方很多，很底层，目前使用临时的解决方案(网上其他方案都无法彻底catch这个异常，有这个烦恼的，请查看下面的代码)，对异常进行try-catch 处理，具体代码如下：

public class LinearLayoutMgr extends LinearLayoutManager {
    public LinearLayoutMgr(Context context) {
        super(context);
    }

    public LinearLayoutMgr(Context context, int orientation, boolean reverseLayout) {
        super(context, orientation, reverseLayout);
    }

    public LinearLayoutMgr(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }

    @Override
    public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) {
        try {
            super.onLayoutChildren(recycler, state);
        } catch (Exception e) {
            e.printStackTrace();
            LogUtil.d("catch exception");
        }
    }

    @Override
    public void scrollToPosition(int position) {
        try {
            super.scrollToPosition(position);
        } catch (Exception e) {
            e.printStackTrace();
            LogUtil.d("catch exception");
        }
    }
}

在初始化RecyclerView 的时候，使用这个LinearLayoutMgr 代替系统的LinearLayoutManager即可
